O2Cs new footwear range brings a unique outsole design combined with ultra-lightweight uppers and a complete anatomic design based on the foot's natural movement when pedalling. Steven Nemeth, founder/designer at O2C shoes, has a long history in technical cycling footwear. His journey started nearly two decades ago when he created Bonts unique bathtub shoe design. Since then, his shoe designs have been worn for 36% of all Olympic track cycling medals over the last five Games. They've also seen victories in the Olympic time trial, UCI BMX World Championships, Tour de France, Giro dItalia, La Vuelta, Paris-Roubaix, and in both mountain bike and BMX World Cups. Now, Nemeth has branched out on his own with a new shoe brand, O2C, releasing a range of new low-profile, lightweight, yet fully anatomically correct performance shoes.

Warren Rossiter / OurMedia Nemeth's softly spoken Australian lilt masks a designer whos always looking to improve, learn and be bold. In his opinion, much of cycling shoe design is hampered by tradition, with shoes designed and made the way they always have been, rather than using the latest biometric learnings. "Ive always looked to create shoes that mirror the way your foot moves," he says. "If that means approaching the construction differently, changing the norm and completely reshaping the shoe, then so be it." O2C's 10 key elements of a cycling shoe 1. Heel cup The heel cup and outsole work in combination for stability and a secure fit. Warren Rossiter / OurMedia "The heel anchors every pedal stroke, yet many shoes allow the rear of your foot to move under load," Nemeth says. Weve designed a heel cup that securely cradles the calcaneus [the large heel bone]. This is done to reduce lateral movement and keep your foot aligned. In turn, that improves power transfer and minimises heel lift. The added benefits are that this should reduce friction and improve long-ride comfort. 2. Toe-box shaping The midfoot is anatomically shaped to reduce creasing of the upper material. Warren Rossiter / OurMedia Nemeth's original Bont shoes were known for their broad, blunt toe-box design. They looked worlds away from the classic tapered-toe shaped shoes we were used to. The new O2C toe box falls somewhere in between. It does, however, look more like the natural shape of a foot. Nemeth explains: "The toe-box shape follows the natural metatarsal parabola. The metatarsal parabola is the natural curved arrangement of your metatarsal bones (the jointed series of long bones in your foot from your toes back). We did this so your foot has more natural toe splay and reduces compression, he says. The goal here is to spread the load, prevent nerve irritation (numbness) and reduce the chances of hot spots. 3. Low stack height Low stack height has been talked about a lot recently, with new pedal/shoe systems from Q36.5 and Ekoi/PW8. So its no surprise that any new shoe will make this the focus of the outsole design. 4. Last construction The interior of the O2C RK1 is as well finished as the exterior. Warren Rossiter / OurMedia Still today, lots of cycling shoes prioritise aesthetics over anatomy," says Nemeth. "That compromises both the fit and your foot alignment. "Our last is completely new and based on a true anatomical shape, based around natural foot biometrics. We aim to balance out pressure distribution, keep your foot aligned correctly and keep the foot secure without compression. 5. Carbon soles Both the RK1 and RS1 use a Toray T800 unidirectional carbon fibre outsole. Warren Rossiter / OurMedia All of the O2C shoes, from the base model RC1 through to the flagship RK1, use full carbon fibre soles. Nemeth believes such a key element of any cycling shoe shouldnt be compromised with lesser materials. The outsoles throughout O2Cs shoes, with what weve launched today and whats coming, will always have full carbon soles," he says. "For the ARC design of our outsole, we couldnt achieve what we need from an outsole without carbon. The soles all use precision-layered Toray carbon fibres to provide the exceptional stiffness combined with a low stack height of just 3.2mm. By using load-specific fibre orientation, we can control rigidity and torsional stability whilst keeping our 3D anatomical shoe shape. One of the key elements in the outsole is the change in fibre orientation and construction forward of the super-stiff cleat plate. Nemeth has introduced a small element of flex here. Thats not only to enhance the comfort of the toe box, but also to make walking in the shoes easier. Nemeth's years of experience informed him that super-stiff, rigid outsoles, when walked in over time, can create a stress point in the outsole, which in extreme cases has led to failure cracks in the sole. That's something he wanted to prevent in the new designs. Unlike many manufacturers, who use one carbon outsole across multiple sizes, O2C made the decision to make individual moulds for each size, in standard and wide fits. Nemeth says: The priority is to get the fit as exact as possible. Its obviously much more expensive to produce moulds for every size, but I didnt want to compromise all of the work weve done over the years developing the O2C range by saving a few dollars in manufacturing. 6. Foot cradle and wrap construction The RS1 is designed for sprinters. You can see the wrapover shape clearly here. Warren Rossiter / OurMedia The shoe's upper uses a wrap shape, with a single-sided tongue that enables the upper material to wrap over. Nemeth claims this design more closely follows the foot's natural contours, better supporting the midfoot and helping to anchor the heel. The result is a claimed secure and stable fit that doesnt restrict your foot's natural movement. I have noticed the side profile of the O2C shoes has much less voluminous height than other models, and from my short time trying out the shoes, it appears to give a sock-like fit thats enhanced by the knit construction on both the RS1 and RK1. 7. Midfoot stability The O2C design doubles up on midfoot support by reinforcing the upper to stabilise the foot where collapse is most likely under load. The O2C design, Nemeth explains, "Controls excessive pronation [when your foot naturally rolls inwards] and rotation [where your feet either splay outwards or your toes point inwards]. "By controlling these elements with a combination of the upper design and construction, combined with the outsole design, we can deliver greater stability. That means sustained power over long rides." 8. Cleat position and adjustment Everybodys pedal position is different, so weve given the O2Cs outsole extended fore-aft adjustment," says Nemeth. "That means more precision to get the optimal alignment. Thats key to both comfort and power transfer, coming as a result of reduced joint strain and more support thanks to being able to get your cleat position just right. 9. Arch-support system O2C has designed insoles that mirror the shoe's anatomical shape. Warren Rossiter / OurMedia The O2Cs outsole and footbeds combine to create dual-arch support for both the medial arch (the longest arch that runs along the inner foot) and the transverse arch (across the midfoot). By maintaining neutral alignment during the power phase, you reduce plantar strain, and reducing these repetitive stresses helps reduce the causes of plantar tears, which can be incredibly painful, says Nemeth. "It also means by better distributing the load, your up-pedalling efficiency helps sustain your output for longer. 10. Sole stiffness and carbon engineering The RC1 uses a 3K woven carbon fibre outsole. Warren Rossiter / OurMedia Nemeth explains that sole stiffness in the right places is a key element of a top-performing cycling shoe. We only use high-grade Toray fibres, you wont find any blends or nylon in any of our shoes at any price, ever," he says. "By using precise layups that maximise stiffness-to-weight ratios, weve been able to create a very lightweight, thin, yet very durable sole. O2C shoe range The range-topping RK1. Warren Rossiter / OurMedia At launch, there are three road-shoe options from O2C, with a lightweight high-summer triathlon shoe in the wings (the RT2), and gravel and aero-road options due later in the year. At the top of the range is the flagship AXIS RK1. This uses a knitted upper, bolstered with a reinforced midfoot, and a 3D-shaped T800 Toray carbon fibre sole. The twin polished alloy dials are O2Cs own design, with two-way micro-adjustment and pop-out release. O2C decided that producing its own dials, rather than opting to buy them in from Boa, was the best option to keep costs down for the end user and provide flexibility to refine the design. The RK1 is a very lightweight shoe. Warren Rossiter / OurMedia My test pair of AXIS RK1s weigh in at 243.4g each for a size 45, making them some of the lightest road shoes available. They're bested only by Specializeds featherweight S-Works Torch Remco, at 300g a pair (549), and Nimbls 480 Ultimate Glide (358g a pair). The RK1s are priced at 389.95. The O2C RS1 is designed for maximum foot control and is designed for sprinters. Warren Rossiter / OurMedia Second in the range, at 359.95, and weighing just over 7g more per pair (247g each), are the AXIS RS1s. They have a larger wrapover section for increased midfoot stability. With more aggressive upper venting, the AXIS RS1 is the sprinter's option compared to the RK1s climbing intentions. The RS1s' 247g weight (size 45) is impressively light. Warren Rossiter / OurMedia The base model of the three-tier road shoe line-up is the 174.95 Vector RC1. These shoes share the same core engineering as the range-topping model, but forgo the unidirectional T800 Toray carbon for a more cost-effective 3K woven Toray fibre. The upper is made from a more traditional, yet still lightweight microfibre rather than a 3D knit. The base-model O2C RC1 has plenty of laser-cut venting in the microfibre upper. Warren Rossiter / OurMedia Theres plenty of breathability on show thanks to the myriad laser-cut holes in both flanks, on the toe box and through the tongue section. For a simpler shoe, the weight is impressively low at only 248.1g each for a size 45. These are some of the lightest sub-200 shoes weve seen. The RC1 is very light for a sub-200 shoe.
